The invention relates to a method of performing signalling and media conversion in a multioperator environment. The invention comprises receiving a signalling from a first operator; detecting a second operator of the signalling; checking information of the second operator from a database; carrying out at least one conversion to the signalling from the first operator; and transmitting the signalling to the second operator.

Conversion system and method in multioperator environment

When a connection is established between user terminals in a system supporting the separation of control traffic and user traffic into separate network nodes, the routing of user traffic is optimized by not reserving resources for the user traffic in the home network (H-MSC) of a user terminal if the user terminal is roaming (-).

Node, system and method for routing traffic in communications system in which call control and signaling is separated from traffic

An apparatus receives a protocol invitation communication from an originating operator and targeted to a receiving operator in a communications system. The apparatus intercepts the communication and checks whether the originating operator and the receiving operator use the same protocol for the protocol invitation communication. If the receiving operator uses another protocol, the apparatus performs a conversion from the originating operator's protocol to the receiving operator's protocol and forwards the converted protocol invitation communication towards the receiving operator.
